[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously; it is widely used in industrial multi-joint manipulators or multi-degree-of-freedom machine devices, which has a certain degree of automation and can realize various industrial processing and manufacturing functions relying on its own power source and control ability; the robot chassis is an important part of the robot, mainly used for the installation or movement of the robot.

[0003] In the Chinese patent with the publication number CN219882533U, a robot anti-collision chassis is mentioned. The shaking frequency of the robot is reduced through a shock absorption mechanism. At the same time, the horizontal movement of a cylinder drives a rack to move, and then the rotation of a speed control plate is controlled. The moving speed of the robot on the ground is reduced through the friction between the speed control plate and the ground, ensuring the stability of the items on the robot.

[0004] Although the anti-collision structure is provided in the robot chassis in the above-mentioned prior art, the anti-collision structure is only located on the front and rear sides to prevent collisions during the movement process, and no protection structures are provided on the left and right sides and the four corners. This still easily causes damage to the robot under the impact of external objects. Therefore, we propose an anti-collision mechanism for a robot chassis. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-collision mechanism for a robot chassis to solve the problem that no protection structures are provided on both sides and the four corners in the prior art, which still easily causes damage to the robot under the impact of external objects.

A guiding component is arranged on the outer side of the chassis main body. The guiding component includes fixed rods. The two fixed rods are symmetrically distributed on the outer side of the chassis main body. The same guiding roller is arranged on the opposite surfaces of the two fixed rods.

[0008] The protection component includes a buffer spring, the buffer spring is fixedly connected to the outside of the chassis main body, the other end of the buffer spring is fixedly connected with a mounting plate, the outside of the mounting plate is fixedly connected with a rubber strip, the outside of the rubber strip is arc-shaped, a circular hole is opened on the outside of the chassis main body, a circular block is slidably connected to the inside of the circular hole, a through hole is opened through the outside of the circular block, and a counterweight is arranged on the top of the chassis main body.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1 - 4 As shown, the present utility model provides a robot chassis anti-collision mechanism, including a chassis main body 1. A mounting frame 2 for fixing the robot is fixedly connected to the top of the chassis main body 1. A robot connecting piece 3 is arranged on the top of the mounting frame 2. A protection component 5 is arranged on the outer side of the chassis main body 1. A guiding component 4 is arranged on the outer side of the chassis main body 1. The guiding component 4 includes a fixed rod 401. The two fixed rods 401 are symmetrically distributed on the outer side of the chassis main body 1. The same guiding roller 402 is arranged on the opposite surfaces of the two fixed rods 401. A rubber sleeve 403 is fixedly connected to the outer side of the guiding roller 402. The rubber sleeve 403 is made of a high-damping rubber material and has good anti-impact performance. The four guiding rollers 402 are arranged in a rectangular shape at the four corners of the outer side of the chassis main body 1. The four guiding rollers 402 protect the chassis main body 1 from all around. The inner side of the guiding roller 402 is movably connected to a transmission rod 404 through a bearing. Under the action of the transmission rod 404, the guiding roller 402 can rotate. The transmission rod 404 is fixedly connected to the opposite surfaces of the two fixed rods 401;

[0024] The protection component 5 includes a buffer spring 505. The buffer spring 505 is fixedly connected to the outside of the chassis main body 1. The other end of the buffer spring 505 is fixedly connected to a mounting plate 502. When the mounting plate 502 moves towards the chassis main body 1 under the impact force, the moving mounting plate 502 will squeeze the buffer spring 505. Under the action of the elastic force of the buffer spring 505, the impact force is weakened to achieve the purpose of protecting the chassis main body 1. A rubber strip 503 is fixedly connected to the outside of the mounting plate 502. The rubber strip 503 is specifically a high-damping rubber and has a good protection effect when subjected to an impact force. The outside of the rubber strip 503 is arranged in an arc shape. The arc-shaped setting can prevent damage to the human body or other objects when they are impacted. A round hole 504 is opened on the outside of the chassis main body 1. A round block 508 is slidably connected to the inside of the round hole 504. The round block 508 can move within the round hole 504. When the round block 508 moves within the round hole 504, friction is generated. A through hole 507 is opened on the outside of the round block 508. The through hole 507 is used for air to be discharged from the round hole 504 or external air to enter the round hole 504 when the round block 508 moves within the round hole 504. A counterweight 501 is arranged on the top of the chassis main body 1, and the counterweight 501 increases the overall stability of the chassis main body 1.

[0025] In a further embodiment, referring to Figures 1 - 4 , a round rod 506 is fixedly connected to the outside of the round block 508. The round rod 506 is fixedly connected to the outside of the mounting plate 502. The round rod 506 is used for connecting the mounting plate 502 and the round block 508, and the round block 508 can be driven to move when the mounting plate 502 moves.

[0026] In this embodiment, under the action of the round rod 506, the mounting plate 502 and the round block 508 are connected. When the mounting plate 502 moves under the impact force, it will push the round block 508 to move within the round hole 504, and the generated friction weakens the impact force, and cooperates with the rubber strip 503 and the buffer spring 505 to protect the chassis main body 1.

[0027] In a further embodiment, referring to Figures 2 - 3 , the counterweight 501 includes a mounting groove 5011. The mounting groove 5011 facilitates the installation of the counterweight block 5012. The mounting groove 5011 is opened on the top of the chassis main body 1. A counterweight block 5012 is arranged inside the mounting groove 5011, and the counterweight block 5012 weights the chassis main body 1.

[0028] Specifically, both the mounting groove 5011 and the counterweight block 5012 are arranged in a special shape, and the inside of the mounting groove 5011 is adapted to the outside of the counterweight block 5012.

[0029] In this embodiment, the chassis main body 1 is counterweight protected under the action of the counterweight 501, so that its weight is increased, and it can be more stable under impact and will not tilt or topple.

[0030] In this embodiment, when impacts occur at the four corners of the chassis main body 1, the impact force will cause the guide roller 402 to rotate, thereby guiding the direction of the impact force and reducing the damage to the chassis main body 1 caused by the impact force.

[0031] The working principle of the present utility model is as follows:

[0032] During use, it is connected to the robot through the robot connecting piece 3 and the mounting bracket 2. When the robot hits a building during movement or placement, or when an external force hits the robot chassis;

[0033] When the impact is on the periphery of the chassis main body 1, the impact force will first contact the rubber strip 503, and then push the mounting plate 502 to move towards the chassis main body 1. When the impact force pushes the mounting plate 502 to move, the moving mounting plate 502 pushes the round block 508 to move in the round hole 504 through the round rod 506. When the round block 508 moves towards the inside of the round hole 504, the extrusion of the round block 508 will cause the air in the round hole 504 to be discharged through the through hole 507, thereby generating friction, and cooperating with the buffer spring 505 and the rubber strip 503 to weaken and offset the impact force, and protecting the periphery of the chassis main body 1;

[0034] When the impact force is at the four corners of the chassis main body 1, the impact force will cause the guide roller 402 to rotate, and the rotation of the guide roller 402 will change the direction of the impact force, thereby reducing the damage suffered by the chassis main body 1;

[0035] The counterweight 501 is located in the middle of the chassis body, increasing the weight of the chassis main body 1, achieving the purpose of improving stability and preventing toppling.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
